A110



The Doepfer A-110 is a voltage-controlled oscillator. This VCO's frequency range is about eight octaves. It can produce four waveforms simultaneously: square, sawtooth, triangle, and sine wave. The Frequency or pitch of the VCO is determined by the position of the octave (Range) switch and tuning (Tune) knob, and by the voltage present at the CV inputs. Frequency modulation (FM) of the VCO is therefore a possibility. Footage (the octave of the fundamental) is set by the Range control, and Fine tuning controlled by the Tune knob.

You can control the pulse width of the square wave either by hand, or by voltage control - Pulse Width Modulation (PWM).

This module has a maximum current draw of 70mA. It requires 10 TE/HP worth of space to fit in a Euro rack frame

Extra
The a110 reacts to negative voltage as well and can go into sub audio range when presented a negative voltage.
